45mm 大型圓形街機風格按鈕（藍色）

The blue LED glow is surprisingly bright and even, making it easy to see which button is which even in a dark room. The micro-switch feels satisfyingly crisp under the finger, just like the old arcade cabinets I remember.

Installed these on my arcade cabinet and the micro-switch has a satisfying, crisp click. The blue LED ring really pops against the black control panel.

The LED ring is bright enough to see in my brightly lit workshop, and the adapter ring made mounting into my control panel a breeze. Everything fit together perfectly right out of the box.
